What’s regsvr32.exe (Microsoft(C) Register Server)? Is it safe or a virus?

Regsvr32.exe, which stands for Microsoft(C) Register Server is a command-line utility in Microsoft Windows that is used to register and unregister ActiveX controls and Dynamic Link Libraries (DLLs) in the Windows Registry.

When a DLL or ActiveX control is registered, it allows applications that require them to locate and use them. It is commonly used for installation and troubleshooting of software applications that utilize these types of files. Regsvr32.exe is typically used by system administrators and software developers to manage the registration and unregistration of DLLs and ActiveX controls in the Windows OS.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
